sensitivity of an electromagnetic type metal detector is directly related to stability, the higher the required sensitivity, the more frequently the rebalancing controls will have to be adjusted. thus, for maximum sensitivity in the head ,the use of automatic drift compensation network is necessary in order to cancel out the signal resulting from a slow drift in the coil system due to the tempe...

Having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. Finding a white-box mathematical model for weight vs. time curves of Electrophoretic Deposition (EPD) using large and small signal analysis has been studied thoroughly in the present investigation. Weight-Time curves of nano-Mullite suspension have been tr...

This paper describes recent work on small-signal stability, model order reduction and power system harmonic analysis carried out in CEPEL, the Brazilian Electrical Energy Research Center. CEPEL has developed, along the last three decades, a suite of power system analysis tools that are in current use by most of the Brazilian electrical utilities.

accumulation of unmanaged industrial solid waste, especially in developing countries has resulted in an increased environmental concern. in view of utilization of industrial solid waste the recycled paper mill waste (rpmw) – cement composite bricks were designed and developed. in order to investigate the environmental performance of sustainable construction materials two small scale model house...

Voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. This phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. In this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...

Signal optimization is affected during radio links between a transmitter and a receiver located in adjacent material media with differing optical densities. The optimization is carried out via the automated control theory method. The radio signal obtained after the optimization is coordinated with the two media's electrical characteristics simultaneously; and this enables low power and small an...
